Concrete FAQ for Lake County & Kenosha County

The questions we get most, answered plainly.

What areas do you serve?

Every town in Lake County, Illinois, plus Barrington Hills, and Kenosha County, Wisconsin as far as Bristol, Twin Lakes and Powers Lake. Each town has its own page.

Do you do both tear-out and the new pour?

Yes, with the same crew. There is no gap between trades and nobody to point fingers at but us.

How do I get an estimate?

Call or email and we come out and look at the job. Estimates are free and we quote from the site rather than over the phone.

When can concrete be poured here?

Roughly April through November for exterior work. Cold-weather pours are possible with blankets and mix adjustments but they cost more and carry more risk.

How long before I can use new concrete?

Foot traffic the next day. Vehicle weight after about seven days in normal conditions. We give exact guidance based on the temperatures during your pour.

Do you handle permits?

Public way work and anything in the village right-of-way generally needs a permit, and we handle the application and inspection scheduling.

Do you work in Wisconsin as well as Illinois?

Yes. Kenosha County is inside our normal radius from Waukegan, out to Bristol, Twin Lakes and Powers Lake.

Will you tell me if I only need a repair?

Yes. Section replacement and slab lifting cost a fraction of a tear-out, and we would rather quote the job you actually need.

How long does a concrete driveway take?

Two to three days of tear-out, base prep and pour work, plus cure time. Weather moves that. You get the full timeline at the estimate.

How long before I can drive on it?

About seven days in normal conditions for vehicle weight, though concrete keeps gaining strength for weeks. You can usually walk on it the next day.

How thick should a driveway be?

Four inches on a properly compacted base for standard residential use. Heavier loads mean thicker concrete and more reinforcement.

How much does a concrete patio cost?

It depends on square footage, finish, access and whether an old slab has to come out. We quote after seeing the site rather than guessing from a phone call.

How long does a concrete patio last?

On a compacted base with correct jointing and drainage, decades. The failures we get called to fix are almost always base or grade, not the concrete.

Can you pour a patio over an existing one?

Only where the existing slab is sound, and even then it raises the height against your door threshold. Usually the old one comes out.

How much more does stamped concrete cost than broom finish?

Noticeably more, because it is more material, more labor and a crew working to a set window. We quote it against a broom-finish price for the same area so you can see the difference.

Is stamped concrete slippery?

It can be when wet, especially smoother patterns. We add a slip-resistant additive to the sealer where the surface borders a pool or takes steady rain.

How often does stamped concrete need re-sealing?

On a cycle measured in years rather than seasons, and sooner on a driveway than on a covered patio. We give you the interval for your specific surface and sealer.

Who is responsible for the sidewalk in front of my house?

The public walk is village property, but responsibility for repair varies by municipality and by program. We tell you what applies at your address before quoting.

Can you replace just one section?

Yes. A single lifted or cracked flag can be saw cut out and replaced. If a tree root caused it, that has to be addressed too.

Do I need a permit to replace a sidewalk?

For public way work, generally yes. For a private walkway inside your property line, generally no.

How thick should a garage slab be?

Four inches on a compacted base is standard residential. A lift, a truck or heavy shelving means thicker concrete and more reinforcement.

Why does my garage floor hold water at the back?

It was poured flat or pitched the wrong way. Meltwater runs off vehicles and has nowhere to go. Sometimes a section replacement fixes it; sometimes the floor comes out.

Can you pour a slab for a new detached garage?

Yes, including the thickened edge or footing your village requires and anchor bolts set while the concrete is wet.

Can my crumbling steps be repaired instead of replaced?

Often, if the structure underneath is sound. Spalled noses and chipped edges rebuild well. Settled or separated flights do not, and patching those is wasted money.

Why did my stoop pull away from the house?

It settled, usually because it was poured on backfill that was never properly compacted, or because it has no footing below frost depth.

Do steps need a footing?

A flight of any height generally does, below frost depth, or it rides up and down with the seasons and separates from the house.

Is it cheaper to repair or replace?

Repair is cheaper when the concrete is sound and only the base or surface failed. Once a slab has broken into rocking sections, replacement is the durable answer.

What is slab lifting?

Drilling small holes in a settled slab and pumping material underneath to raise it back to grade. It costs a fraction of replacement and works well on slabs that settled as one piece.

Why is my concrete flaking?

Usually salt, a mix without air entrainment, or troweling while bleed water was still on the slab. Light scaling can be resurfaced; deep scaling means replacement.

Do you haul the concrete away?

Yes, haul-off is part of the job, and we separate clean concrete for recycling where the facility takes it.

Can you remove concrete in a tight backyard?

Yes. Tight access means hand-guided breaker and wheelbarrow rather than machine, which is slower and gets priced accordingly rather than discovered mid-job.

Do you fill in the hole afterward?

Yes. We backfill with suitable material, compact it and grade so it drains instead of becoming a low spot. Topsoil and seed can be included.

Still got a question?

Call and ask. We would rather talk you out of work you do not need.
